THOMAS GALT, OF STERLING, ILLINOIS.

Specification forming part of Letters Patent No. 48,269, dated June 20, 1865.

To all whom it may concern Be it known that I, THOMAS A. GALT, of Sterling, in the county of Whitesides and State of Illinois, have invented a new and Im proved Seed-Sower and Gultivator; and I do hereby 'declare that the following is a full, clear, and

exact description thereof, which Will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side sectional view of my invention, taken in the line x, Fig. 2 5 Fig 2,

Aan inverted plan of the same 5 Fig. 3, a vertical section of a portion of the same, taken in the line y y, Fig. 2; Fig. 4, a detached outer view ofa portion of the seed-slide.

Similar letters' of reference indicate like parts.

This invention relates to a new and improved means for regulating the discharge of the seed, and also for operating the seed-slide, whereby the amount of seed to be sown on a given area may be very nicely graduated and by a very simple arrangement. j

The invention also relates to a novel and improved mode of attaching theteeth or coverers to the machine, whereby the former may be made to penetrate into the earth at a greater or less depth, as occasion may require.

The invention further relates to a means employedforelevating the teeth orcoverers,where by the same may all be raised simultaneously by actuating a single lever.

A represents a rectangular frame, in which a seed-box, B, is placed, the latter extending the whole length of the former. The frame A is mounted on two wheels, O C, and the seedbox B is provided with an inclined bottom, a, a slide, D, being over a slot or opening, b, which extends the whole length of the lower part of the rear side ot' the seed-box, andis allowed to work freely in guides ror supports c, arranged in any proper Way.

The slideD is perforated with holes of semielliptical form, and these holes are covered by a sliding plate, E, which are also perforated with semi-elliptical holes d. The plate E is fitted in guides e, attached to the slide D, and said plate is providedwith a rack, f, at a portion of its under side, into which rack a toothed segment, g, gears, the latter having a handle, h, attached to it, by moving which the plateE may be adjusted to bring the perforations of the slide l) and plate E more or less in register with each other, so as to increase or diminish the capacity of said openings and regulate the flow or discharge'of the seed, as may be required. This will be fully understood by referring to Fig. 4.

To the slide D, at the side opposite to that where the segment g is attached, there is secured a rack, i, into which a toothed segment, j, gears, the latter being provided or formed with an arm, F, and working on an axis, k, which is concentric with the segmentj. (See Fig. 2.) The outer end of the arm F is connected by a pitman, G, with a crank, Z, on a small shaft, m, which ha-s a bevel-pinion, In, upon it, said pinion gearing with a bevelwheel, o, on a shaft, H, which forms the axle of one of the wheels O, as shown in Fig. 2. This shaft H is allowed to slide in its bearings for the purpose of throwing the wheel c in and out of gear with the pinion n, and said shaft is thus adjusted by means of a lever, I, the lower end of which is forked and fitted over a grooved wheehp, on the shaft H. (See Fig. 3.) From the above description it will be seen that when the wheel o is in gear with the pinion n, and the machine is being drawn along, a reciprocating motion will be communicated to the slide D through the medium of the rack i and toothed segment j, andthe seed discharged through the perforations of the slide D and plate E, the flow or discharge of the seed being regulated by the adjustment of the plate E through the medium 'of the rack f and toothed segment g, previously alluded to.

To the back part of the frame A there are attached three metal plates, J J, one at each side and one at the center, and to each of these plates a bar, K, is secured by a bolt, q. Thesel bars K are connected at their outer ends by a shaft, L, and the inner ends of said bars are ot' bent form, as shown at r, and have a bolt, s, passing through them and through any of a series of holes, t, in the plates J, the holes t being made in the arcs of circles of which the bolts q are at the centers. (See Fig. l.) In consequence of the holes t and bolts s, the bars K may be adjusted at a greater or less degree of inclination, for the purpose of regulating the depth of the penetration of the teeth or coverers M, Which are attached to the bars N, fitted loosely ou the shaft L. (See Figs. l and 2.) n

O is a bar Which is underneath the bars N of the teeth or coverers M, and is connected at its ends to arms P, which are fitted loosely on the shaft L. This bar O has a chain, Q, attached to ir, which passes over a pulley, u, in a horizontal arm, It, on frame A, and is connected to the lower end of a lever, S, provided with a segment-arm, T, over which the chain Q passes. The lever S has its fulcrum o at the rear of the seed-box B; and it will be seen that by shoving the lever S forward the bar O Will be raised, and the bars N, and consequently the teeth and coverers, all raised sim ultaneously. The teeth or coverers may be retained or held in an elevated state by placing the front end' of the lever S under a hook, U, at the back part of the draft-pole.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t- The method of' operating the slide D through the medium of the rack t', toothed segment j, and gearing n o, in combination with the sliding plate E, which is moved upon the slide D by means of the rack j' and toothe segment g, the Whole arranged as described and represented.
